To ALL WHOM IT MAY CONGERN.

Benit known that we, HENRY B. ABNOLDTand JOHN GRLYMMVot the ,county oi St. Louis, and State of' Missouri, have made certain new and useful Improvements in Cultivators; and we do hereby declare tha-t the following is e. full end clear description thereof, reference beingv hud to the accompanying drawings, and to the letters of reference marked thereon.

The object of'thie invention is to produce e. cultivator that :will not only cultivate andloosen the soil to any requireddepth, but also, at the seme time, cut oli` the weeds between the rows of plants that are cultivated by it, and thus edectuelly stop their further growth. The devices employed are the usuel cultivotor-teeth, end e, knife, scraper, or cutter for destroying the weeds, the whole attached to and combined with e plough-beam and handles, in the usual manner of cultivetox's; and,liu addition to the improvements above alluded to, there are others for the'purpose ofadaptiug the plough-handles to the size' of the person operating the oultivutor, and still others for the purpose ot regulating thev depth to which the cultivstor end scraper or cutter is to run in the ground.

Tovenehle those skilled in the art to molte and use our improved cultivetor, We will proceed to describeits construction endeperetion.

Figure 1, ofthe drawings, is s side elevetiono' one ot the improved coltivatore, with one of the handles removed.

Figure 2 is c. plan oi the cultivate?.

The beatm A will be cf Wood, es usuel, end e shovel-plough, B, or some other suitable cultivating-instrument, T.vill be eiiixed to the forweid part cf it. A. coulter or1 cutter, B', will immediately precede the plough B, and open the ground. Eirectiy behind the plough B,*v .nd,liko it,n.ttrched vto the beam A, is the weed-cutter C, which isn. horizontal blade, sharpened ut its foi-Werd edge, the central part of which should be farther edvanced than the drinks, thus forming thc-front edge of the seid blade somewhat in the shape of the letter v, with its apex in the centre, und farthest advanced, thus' enabling the blade to strike u glancing out on the weeds, and thereby cut them ol et a. stroke. The she-nk Cl of the weed-cutter extends up through the beam, and also through s metal' staple, C5, aiiixed to its top side. The screw-nuts e c nre screwed on to the threads out in the upper end of the shan a' C1, one ci them above the Astaple C2, und the other one belen it. By Ineens oi those tivo scr'ewnuts, the weed-cutter may be set higher ori lower,l ns muy he desired, and thus the depth of' out regulated.

The front end of the beam A is provided with the usun ring, a, and'clevis, al, which muy he so adjusted as to regulate the line of dicugl1t,in such o. manner 'ne to ineke the plough run more or less deepJ as maybe desired..4 n case, however, this device for regulatingthe depth may not prove suicient for deep ploughing.l a, movable arm, A1, is attached to the upp'er side ofthe beam, near its front end, and is provided-with n. draughtring, a, to which the team .may be attached. 4The erm A! may be elevotedcr depressed, as may he desired, :ind secured in position by-means of the adjustingpin as and the graduated rack A2.

A rollen-D, having its hearings in the inclined arms d and the graduated rack cZ, muy be moved up' or down, end 'secured in any desired position, by means ottho pin d, which passes through the seid ruchd, and also thrcughthe beam A, and holds the ports' in thewposition, desired. The roller D, when once xed in its proper position, is intended to roll along over the'surfeco of the ground, and so regulate lthe depth of the plough and Weed-cutter. i

The plough-handles A ere tc be xed to the sides of 'the beam L bymeens' ol the pivot-pin ai, so that their beek ends may be 'elevated or depressed, to accommodate n. short or a. tall person. The curved rack Afond set-l screw a5 will serve to secure .the hack endsof the handles et 'their proper elevationsi Having described our invention, what we claim, is-

l. The weed-cutter C, when'combined with ai cultivutor, A B, as vund -for the purpose herein shown and described.. l

2. We claim themovoble arm A1, when combined withl the .plough-boem A, es described, and for the purl 'pose set forth. f

3. We claim the piough-handles A3 and the curved roel.: A, for t-he purposes herein set forth and described.

In testimony of which invention, we hereunto .s etour hands, this 1st deyofJuly, A. D. 1867, in presence of- I H. B. ARNOLDT,
